Python’s new t-strings

by making it a generic `t` you lose explicit syntax highlighting. Where something like JS template`string` could determine which syntax to use based on the template value.

I supposed when assigning it to a, variable: SyntaxRecognizableTemplate, you could give it the hint necessary.

was this discussed in the PEP?

*edit: reading the PEP-750[1] it doesn't seem like it..

[1] https://peps.python.org/pep-0750/#the-interpolation-type

We pushed these questions out of the PEP to keep its scope constrained. (See https://peps.python.org/pep-0750/#mechanism-to-describe-the-...)

But yes, the PEP leaves open an important question: how will tools decide to work with common types of content in t-strings, like HTML or SQL?

There are simple approaches that can be taken in the short term (content sniffing) and more robust approaches (type annotations, perhaps) that will take time and the broader tooling community to develop.

It was discussed in the first revision and discussion of the PEP. The decision was made to move that to follow-on work, as we discovered more about what tooling needs.

As an example, I was excited about using `Annotated` on the function to indicate the language it expected. Turns out, a lot of linters know nothing about the type system.
